| Abstract: | In the presence of soft-template such as PVP,PVA and CTS,Ag nanoparticles with different morphologies were prepared through liquid phase chemical deoxidization method.The effect factors,such as surfactants,temperature and ultrasonic action were discussed.The products were characterized with transmission electron microscopy(TEM),ultra-violet-visible(UV-Vis),infrared absorption spectroscopy(IR) and X-ray diffraction(XRD).The growth mechanism and the photoelectric properties of Ag nanoparticles were studied. |
